Taxonomic Diversity of Macrobenthos in Shenzhen Baguang Yinyeshu Wetland Park
This paper revealed the taxonomic diversity of macrobenthos in Shenzhen Baguang Yinyeshu wetland park,so as to better protect the macrobenthos resources of the wetland.In January,April,July and November in 2023,the annual survey of macrobenthos in the wetland was conducted,and the taxonomic diversity and tradition-al diversity of macrobenthos in the wetland were calculated based on the survey data,and the correlation between the two diversity indices was analyzed.The results showed that the taxonomic diversity index(Δ)of macrob-enthos in Shenzhen Baguang Yinyeshu wetland park ranged from 42.041 to 45.086,with an average of 43.427.The taxonomic distinctness index(Δ *)ranged from 56.493 to 60.172,with an average of 59.192.The average taxonom-ic distinctness index(Δ+)ranged from 57.813 to 61.674,with a mean value of 59.861,and the variation in taxo-nomic distinctness index(Λ+)ranged from 421.989 to 535.144,with a mean value of 483.162.There was a signif-icant correlation between the taxonomic diversity index(Δ)and the variation in taxonomic distinctness index(Λ+)and the traditional diversity index.However,the taxonomic distinctness index(Δ *)and the average taxo-nomic distinctness index(Δ+)were not significantly correlated with the traditional diversity index.In practical application,researchers can combine the two types of indices to more comprehensively assess and understand the biodiversity of macrobenthos in the study area.
